How To Plant Your Potatoes

How To Plant Your Potatoes

Grow bags for potatoes are an excellent solution for patio or small space gardeners. You can purchase them right from our store. Learning how to grow potatoes in a bag will provide a space-saving solution, and it’s a fun family project.

The bag lets the plant spread out its roots and you can still add layers of soil. The reason for layering is the same as hilling. Potato tubers send out roots at the eyes, which branch out in soil. The more you cover the top of the root zone, the more roots they send out. More roots equal more potatoes. Using potato grow bags allows you to control the region the tubers are planted in and makes them easy to harvest. The spuds will be confined to the bag so all you need to do is dig around to find them. 

Lift up the front flap of our bags for a more convenient way of harvesting below ground growing vegetables.

1.  Fill the bottom with a couple of inches (5 cm.) of soil and compost mix and plant your seed potatoes. Fill with just enough medium to cover the tops of the tubers. Keep the soil mix evenly moist and cover the sprouted potato greens with compost mix as they come up.
2.  Keep them covered with soil as they grow and as the soil level rises. Once the soil is at the top of the bag, allow the plants to flower and die back and then dump out the contents so you can pick through and get all the spuds. You can also harvest young spuds early in the process.

Note:  I cannot express this enough keep them covered always with soil :)
3.  Situate your bags in full sun and keep the soil evenly moist but not soggy. Keep an eye out for pests, especially chewing insects which can affect the vigor of your plants. Occasionally unearth a small tuber and check for any damage to the young potato. If you use clean new compost, you are unlikely to have any major soil borne insect problems.
4.  Start harvesting as soon as you have little potatoes for tender spuds on the grill.
5.  By fall, remove all the spuds to prevent them from freezing and splitting OR bring inside where it is warmer.
Note:  As long as you have good lighting you can grow them inside :)
Potatoes are usually harvested within 6-7 weeks.
Hope this is helpful.  If you have any other questions for us, we'd love to hear them :)

Hey Guys. Amy here with Vigragro. I will respond to both questions as best as I can, but first let me share with you the news of our new courses that are in the works. All Vigragro customers past and present will have access to these resources of interactive videos, courses, and e-learning. Brenda, I would recommend starting with 2-4 tubers per bag. You will see twice that in yield, so you want to make space ahead of time :) Carlos, roll your bags down, and cut your tubers in half, and place them in about 2-4 inches of your soil at the bottom of the bag with exposed side down, then fill with just enough to cover the tops of the tubers. As they begin to develop green shoots, cover with more dirt and unroll bag to that level of new dirt. Continue this process until you have reached the top of the bag. This process is called hilling. Once you have unrolled the bag and made it to the top, let them grow from there. Once the leaves and stem starts to die back, place your bag on a safe surface, and open the flap to harvest. Tip: make sure you water enough to see water drain from bottom, then stop. Overwatering could cause rot of roots. I only water mine when I can feel down with half my finger and soil is almost dry. Hope this helps you both :)

I just planted 2 types of potato seedling in 2 Vigragro bags as instructed but I’m not sure what you mean by “cover sprouted potato greens with compost as they come up.”
2. Keep them covered with soil as they grow and as the soil level rises …." Do you mean cover the potato leaves with compost as they come up? How do I know when to let them come up and flower?
Do you have an instructional video showing all the steps from the very beginning, filling the bags with dirt, placing the potato seedling on top, cover, water and wait until the potato greens come out, cover them etc until the spuds start growing until harvest time?
I think this instructional video will help many of your clients. For now, I can only rate you 2 at best. I’ve been 2nd guessing myself as I prepare the potting mix with the compost, add fertilizer, placed the seedling potatoes on top and covered them with 1-2" of soil and hope they come up.
I’m not sure if you meant cover the leaves as they come up! Hope you can clarify that for me. Your leaflet with the bag give very basic and generic instructions for a first timer like myself. Thanks.
